The First ICMI Emma Castelnuovo Award


The International Commission on Mathematical Instruction (ICMI) seeks nominations for the first award named in recognition of Italian mathematics educator Emma Castelnuovo.

Castelnuovo graduated in mathematics from the University of Rome before World War II. After three years teaching middle school students, she wrote a geometry textbook grounded in the use of concrete materials, looking at and manipulating objects, and discovering their geometric properties. Three decades of classroom service later, the daughter and niece of algebraic geometers became president of the International Commission for the Study and Improvement of Mathematics Teaching (known by the acronym CIEAEM, from the commission's name in French: Commission Internationale pour l'Etude et l'Amelioration de l'Enseignement des Mathematiques). With other CIEAEM members such as Jean Dieudonné, Hans Freudenthal, and Jean Piaget, Castelnuovo's commission produced several books, including one with a chapter she contributed entitled "The object and the action in the teaching of intuitive geometry."

Castelnuovo died in April at the age of 100. To honor her pioneering work, the First ICMI Emma Castelnuovo award for outstanding achievements in the practice of mathematics education will honor persons, groups, projects, institutions, or organizations engaged in the development and implementation of exceptional and influential work in the practice of mathematics education, including

  • classroom teaching
  • curriculum development
  • instructional design (of materials or pedagogical models)
  • teacher preparation programs or field projects

Learn more about nominations, due Monday, 15 December, by visiting this web page of ICMI, a commission of the International Mathematical Union (IMU):


PoW taking place: math problem-solving moment of the week

"Kai P. from Montessori School of Northampton also made a table, but he drew his on paper and sent in a picture. Andrew W. from Birch Wathen Lenox School, whose full solution is below, explained how he spotted and used a shortcut. I want to leave you with a thought from Marina E. of Mesa Union Junior High. She, like many of you, noticed a doubling pattern. But she wondered, 'Why does that doubling trick work?' Here's her explanation ..."

Now taking place: math education conversation of the day

"I am still at the beginning of development, and plan to add more concepts, but I came here to get early feedback to know if you think such a program that, as Gary puts it much better than I did, 'looks over the student as a teacher might do,' can be useful."
- Samuel, posted to the math-teach discussion

Ask Them Anything


In two upcoming live chats, prominent advocates for science and science education invite anyone to "ask them anything" via the Reddit online community.

At 11 AM (ET) on Monday, 1 December, Brian Cox logs on from the UK. The Chair in Particle Physics and Royal Society University Research Fellow at The University of Manchester works on the Large Hadron Collider at CERN. Author of books such as Why Does E = mc²? and Wonders of the Solar System, Cox has presented the BBC TV show "The Big Bang Machine" and hosted the radio series "Moments of genius," "Einstein's letters," and — with comedian Robin Ince — "The Infinite Monkey Cage." A professional musician who failed Maths A level before earning his PhD, Cox received the Institute of Physics' 2010 Kelvin Award "for communicating the appeal and excitement of physics to the general public through the broadcast media."

The following Tuesday, 9 December, at 1 PM, David Pogue returns to Reddit. The founder of Yahoo Tech and author of seven For Dummies books, Pogue has also hosted science shows on PBS's "NOVA," including several on Einstein's brain, and one called "Memory vs. Intelligence." Like Cox, Pogue originally set out in music, too: he conducted and arranged musicals on Broadway for a decade before serving as The New York Times' personal-technology columnist for 13 years.

Through the years, Reddit has hosted many "ask me anything" (AMA) sessions on science:
